To: edk2-devel, devel; +Cc: stefanb, lersek, simon.hardy, Marc-André Lureau
From: Marc-André Lureau <marcandre.lureau@redhat.com>
A following patch is going to use the same configuration for TPM1.2
and TPM2.0, and it's simpler to support both than variable
configurations.

From: marcandre.lureau @ 2020-02-13 13:12 UTC (permalink / raw)
To: edk2-devel, devel; +Cc: stefanb, lersek, simon.hardy, Marc-André Lureau
From: Marc-André Lureau <marcandre.lureau@redhat.com>
Enable TcgPei & TcgDxe modules to initialize a TPM 1.2 device and
measure boot environment.
Tpm12RequestUseTpm() returns success on any TPM interface, including
FIFO & CRB which are TPM 2.0. Check the actual interface with
Tpm12GetPtpInterfaceType(), and only detect 1.2 if it's a TIS.

This matches commit [5] 3103389043bd ("OvmfPkg: Add TCG2 Configuration
menu to the Device Manager menu", 2019-02-11).
... Which was later cleaned up by commit cf3ad972a210 ("OvmfPkg:
reorganize TPM2 support in DSC/FDF files", 2020-01-09).

Again reflects commit [3] 0c0a50d6b3ff ("OvmfPkg: include Tcg2Dxe
module", 2018-03-09).
So, my requests thus far:
(1) Please split this part of the patch into five separate patches, in
parallel to commits [1] through [5].
The messages on the new patches need not be very long, they should
basically repeat the original subject lines, customized for TPM-1.2, and
refer to the TPM-2 commit that they mirror.
(2) Where you add TcgDxe and TcgConfigDxe to the DSC file, I'd prefer if
we didn't duplicate the TPM_CONFIG_ENABLE condition. Can you please add
TcgDxe just above Tcg2Dxe, and TcgConfigDxe just above Tcg2ConfigDxe?
Because, this would be consistent with the rest of the DSC file updates,
as you (nicely) add the TPM-1.2 artifacts just above the TPM-2.0 ones.
(3) In the FDF file, you forgot to add
"SecurityPkg/Tcg/TcgConfigDxe/TcgConfigDxe.inf" (paralleling commit [5]
3103389043bd ("OvmfPkg: Add TCG2 Configuration menu to the Device
Manager menu", 2019-02-11)).

(5) The indentation is not correct; it should be two spaces to the right
of the start of the word "PcdSetPtrS".
(6) IIUC, we shouldn't use the Tpm12GetPtpInterfaceType() function here,
per Jiewen's comment. (Sorry, I can't comment on patch#2.)

Hi Lureau
I don’t think we should expose the TPM Interface type via TpmCommandLib.
That is the TPM device implementation. The TPM device might use TIS/FIFO/CRB, but there might be also other type such as I2C, or fTPM implementation type.
To distinguish TPM2.0 or TPM1.2, the standard way is to send startup command.
Thank you

Thanks for the feedback, unfortunately I don't know how to achieve
this for both tpm/vtpm (uninitialized) & passthrough (initialized).
If the device is uninitialized, sending Tpm12Startup (TPM_ST_CLEAR) to
detect 1.2 in Tcg2ConfigPeimEntryPoint will work, but then
Tpm12Startup () in TcgPei:PeimEntryMA will later fail.
If the device is initialized/passthrough, sending Tpm12Startup
(TPM_ST_CLEAR) will fail, so it could send Tpm12Startup (TPM_ST_STATE)
instead. But that will fail to detect uninitialized 1.2 device.
I am stuck, any help welcome!

For tpm/vtpm (uninitialized), I think you can set PcdTpmInitializationPolicy to 0 in the TPM detection module. As such, the TCG PEI will skip Startup() command.
Please refer to SecurityPkg\Tcg\Tcg2Config\TpmDetection.c.
I am not clear about the passthrough mode.
Which module initializes the TPM ? Can we let this module pass some information ?
Thank you

You should be able to do this in the same way as we do it in QEMU:
https://github.com/qemu/qemu/blob/master/hw/tpm/tpm_util.c#L190
Send a command (non-TPM_Startup) to it and inspect the TAG in the header.
